Remember that the goal is to isolate the k.

-3k + 12 = -6

We want to morph this into something that looks like k =

Subtract 12 from each side to eliminate the 12 on the left side of the equation:

-3k + 12 **-12** = -6 **- 12 **

-3k = -18

Now divide by -3, not -3k, because you want to get rid of the -3 and be left with just the k.

-3k = -18

-3 -3

k = 6. Yes we know that it is a positive 6 because -3 * 6 = -18.

So dividing a negative by a negative yields a positive, just like multiplying a negative by a negative.

Yes, a negative number divided by a negative number gives you a positive number.

If you are trying to solve for k, cancel out the 12 before doing any division.
